Canadian National 7470 is a preserved CN O-18-a 0-6-0 steam locomotive at Conway Scenic Railroad in North Conway, New Hampshire.

History

The locomotive was built by the Grand Trunk Railway at Pointe-Saint-Charles in 1921. The Grand Trunk classified the switcher as F9 Class and numbered it 1795. When the Canadian National Railway absorbed the Grand Trunk in 1923, they reclassified it as an O-18-a and renumbered it as 7470.

After retirement, 7470 was spared scrapping by being sold to Canada Dominion Sugar, where it spent some additional years as a switcher. In 1964, it was purchased by the Ontario government for a transportation museum that never came to fruition, and in 1968 it was sold to Dwight Smith.

Dwight Smith was working on founding the Conway Scenic Railroad, which opened in 1974. Locomotive 7470 was renumbered as Conway Scenic 47 and was the new railroad's only locomotive in its earliest years. The old number 7470 and Canadian National paint scheme were restored in 1988 according to Railfan & Railroad magazine.

In July 2014, It was announced that 7470 will be coming out of service due to a major federally mandated inspection, and it was reported that 7470 would run until January and was taken out of service for two years while the overhaul work is being done. The overhaul work had just begun in January 2015. 7470 ran its last train before its federally mandated inspection on January 3, 2015, for one final Steam in the snow hosted by the Mass Bay Railroad Enthusiasts. It is expected that 7470 will be returned to service in time for Railfan's day in September 2016.
